2 Carbon stars and nebulosity in Cygnus

Not having the day job has given me a new imaging experience – the ability to image during June 🙂  With the day job I used to give up imaging half way through May (if not earlier) due to the … Continue reading

NGC 6791 and Carbon star U Lyrae in the constellation Lyra

Managed to grab 7 x 10 minute subs on all 3 mini-WASP cameras before the cloud I had been watching finally arrived from France.  Glad really as it meant I could have an early 12:30 a.m. night. This is open … Continue reading

A beautiful pair of Carbon stars in Lyra

Last night it was beautifully clear and Moonless and was probably one of the best imaging runs I’ve ever had.  Apart from the highly anti-social hours of course as I couldn’t start imaging much before 11:00 p.m. which meant shutting … Continue reading

Hyperstar III test-shot #2

Hyperstar III test-shot

Recently imaged M57 as a test-shot for the recently flattened M25C chip.  This is 14 x 5-minute subs with a blazing nearly full Moon overhead.  Looks pretty reasonable considering 🙂

The Hyperstar III

The Hyperstar III is so fast that all other amateur imaging systems are extremely slow and have very disappointing performance in comparison – and that includes the mini-WASP array as currently configured.

Feynman’s Legacy

Feynman left us many interesting facts/tools and one of the most powerful I have ever come across was his observation that “The same equations have the same solutions”.  By this he means that equations of the same form have similar solutions.  Now … Continue reading
